Unit: mm
Low drain-source ON-resistance: RDS (ON) = 5.6 mΩ (typ.)
High forward transfer admittance: |Yfs| = 90 S (typ.)
Low leakage current: IDSS = 100 μA (VDS = 75 V)
Enhancement-mode: Vth = 3.0 to 5.0 V (VDS = 10 V, ID = 1 mA)

Weight: 4.6 g (typ.)
Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in
temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e.
operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate
reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/Derating Concept and
Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

Note 1: Ensure that the channel temperature does not exceed 175°C.
Note 2: VDD = 25 V, Tch = 25°C (initial), L = 135 μH, IAR = 70 A, RG = 25 Ω
Note 3: Repetitive rating: pulse width limited by maximum channel temperature
Note 4: The definition of maximum rating condition for both channel temperature and storage temperature range is
derived from AEC-Q101.
This transistor is an electrostatic-sensitive device. Handle with care.
